CONVEYEE.

Application filed January' 10, 1919. Serial IiTo. 270,536.

To all whom it may concern:

Be it known that 1, Jesse E. MCBRIDE, a citizen of the United States of America, residing at Highland Park, in the county of \Vayne and State of Michigan, have in-. vented certain new and useful Improvements inGonveyers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to conveyers of that type designed for the carrying of work in suspension, being applicable to enameling apparatus and other uses.

Among the objects of the invention are, lirst, to obtain a simple and inexpensive construct-ion; second, to reduce the power re quired for the propulsion of the conveyer; third, to protect the suspended work from any dirt' incident to the traveling of the conveyer along its track; and fourth, to obtain various specific advantages as hereinafter set forth.

In the drawings:

Figure l is a cross-section through an enameling oven to which my conveyer is applied M Figure 2 through;

. Figure 3 is an enlarged section of a portion of Figure 1.

In the enameling of large and heavy articles, such as automobile bodies, it has been is a longitudinal section therefound advantageous to convey the work continuously during the coating, dripping and baking steps. The supporting of the work on an underneath conveyer is objectionable, inasmuch as the conveyer will thus become coated with the drippings from'the liquid enamel. On the other hand, where an overhead conveyer is used there is danger of dirt dropping upon the enameled surface and injuring the same. -My improved construction is a conveyer of the overhead type which is so designed as .to effectually protect the work from dirt and also to carry the load with a minimum expenditure of power. V

In detail, A are rail or track members which are mounted upon a suitable framework including spaced hanger supports B secured to cross beams C or other supporting frame. As shown, the hangers B are formed of angle bars D and. E secured to each other by riveting and reinforced by gusset plates F, and the rails are bolted or otherwise secured to the horizontal flanges of the angle bars E, as indicated at G. H 1s a gutter secured to the hangers B and extending between the same, said gutter I being in the form of an angle strip having its horizontal portion H beneath the hangers and a vertical flange H extending upward on the inner side above the plane of the base of the-rails. I are trolleys for traveling upon the tracks A and comprising the cross shafts J with trolley wheels K at their outer ends. Each of these wheels is formed of an annular member Ii sleeved overthe end of the shaft J and having antifriction rolls M between the same and the shaft. At opposite ends of the annular member L are the head members N secured by bolts 0 and serving to hold the rolls from endwise displacement, the inner head member being 'of greater diameter than the member .L to form a flange for the wheel. The wheels are secured from longitudinal displacement upon the shafts by fork members P bolted to the outer end and engaging grooves Q, adjacent to the outer ends of the shafts. The ends of the shafts are bored, as indicated at R, for the introduction of lubricant to the rolls of the bearing.

The shafts J are connected to a conveyer chain S by links S thereof having half bearings for the shafts and caps T clamping the shafts to the bearings by bolts U. W is a work-supporting hanger which is bifurcated at its upper end to embrace the link S andis also bifurcated at its lower end with hooks W on'the furcations, thereof.

the work. The trolley wheels and tracks upon which they run are above the trough members If and any dust or dropping lubricant will be caught by these trough members, thereby effectual y protecting the surface of the work. The line of draft of the chain is in the central plane of the work-supportor other dirt which can drop directly upon ing hanger and is therefore symmetrical with respect to the load and the trolley wheels and tracks This coupled with the fact that the anti-friction rolls reduce the resistance to the minimum and'also the fact that the line of draft is straight greatly reduces the power required for the advancement of the work.

The portion of the conveyer for carrying the load is located within the oven and preferably near its top while the return portion of the conveyer is located above the oven.

What I claim as my invention is 1. The combination with track members, of a conveyer chain provided with spaced links having shaftengaging bearings, shafts clamped in said bearings and extending transversely above said track members, and trolley wheels journaled on said shafts for engaging said, track members, said wheels comprising annular members concentrically spaced from the shaft, rolls between the shaft and annular member, heads at opposite ends of said annular member clamped thereto forming retainers for the rolls, and one of said heads forming a fiange for the wheel, a fork member clamped to one of said heads engaging a groove in said shaft member to retain said trolley wheels from displacement on said shaft.

2. The combination with parallel tracks,

of members engageable with said tracks and movable therealong, a rod between said members, a conveyer chain havinga link fixedly secured intermediate said members to said rod, and a work supporting hanger secured to said rod and depending therefrom and between said tracks.

3. The combination with parallel tracks, of members engageable with said tracks and movable therealong, a connection between said members, a conveyer chain having a link fixedly secured intermediate said members to said connection, and a work supporting hanger bifurcated to engage said connection on opposite sides of said link,

hanger depending from said shaft and between said tracks, and gutters beneath said tracks and trolley wheels and having inner side flanges extendingupwardly to points above the bottoms of said tracks.

5. The combination with parallel tracks, of trolley wheels adapted to travel upon said tracks, shafts extending transversely of.

the tracks and between said trolley Wheels and upon which the later are journalled, a conveyer chain having a series of spaced links with bearings for en aging said shafts, means for clamping said s afts in said bearings, and Work supporting hangers bifurcated to embrace said shaft bearings and engaging the shafts upon the opposite sides thereof.

6. The-combination with track members,

of a conveyer chain provided with spaced links having shaft engaging bearings, shafts clamped in said bearings and extending transversely above said track members, trolley wheels journalled 011 said shafts for engaging said track members, each of said wheels comprising an annular member rotatably mounted upon a shaft, a head at one end of each of said annular members forming a flange for the wheel, and means for securing said head to said annular member, and means secured to said head securing means and engageable with said shaft for retaining each of said wheels upon said shaft.

In testimony whereof I afiix my signature.

JESSE E. MCBRIDE.
